Overview

The DiamondTouch table is a front-projected interactive display that allows up to four users to sit face to face and work together on the same screen. The DiamondTouch hardware enables a class of software known as "single-display groupware" where collaborative work is supported by computer interfaces that allow participants to be physically close. While product literature mentions consumer uses such as gaming, customers of the DiamondTouch are using it for business and office applications.

The principal feature that distinguishes the DiamondTouch table from other multi-touch interfaces, such as the Apple iPhone, HP TouchSmart

DiamondTouch achieves this feature through capacitive coupling between a transmitter array located in the touch surface and separate receivers located in the chair of each user.

The physical set-up of the system consists of the DiamondTouch device connected to a PC via USB cable, and a video projector

History

DiamondTouch technology was developed by Paul Dietz and Darren Leigh at MERL, and presented at the ACM Symposium on User Interface Software and Technology (UIST) in 2001. The hardware complimented other Human-Computer Interaction (HCI) research, including the Personal Digital Historian developed by Chia Shen and others at MERL, and led to developments in tabletop computing, shared display groupware, and touch-based interaction. While the traditional computer interfaces (consisting of a mouse, keyboard and monitor) were originally designed to support individuals, the focus was to create a new type of computer interface to support face-to-face collaboration among small groups of people.

In 2003, MERL started a university loan program in which DiamondTouch tables were provided to universities for research purposes, and tabletop computing research built around DiamondTouch began at research groups including Stanford University

, leading to research papers presented at academic conferences including UIST, ACM Conference on Human Factors in Computing Systems (CHI), ACM Conference on Computer Supported Cooperative Work (CSCW), and International Conference on Human-Computer Interaction (HCII). Research in the field led to the formation the annual academic conference beginning in 2006 called Tabletop (initially, the IEEE International Workshop on Horizontal Interactive Human-Computer Systems or TableTop 2006, and most recently the ACM International Conference on Interactive Tabletops and Surfaces or Tabletop 2010).
